led

Simple C software that monitors keyboard layout change - to toggle audio LED on laptop Lenovo Thinipad T430. Bonus: mute the audio :)

Control the brightness of backlight and keyboard LED devices on Linux.

C/C++ GNU/Linux kernel module to drive via SPI a MAX7219 controlled chained array of 8x8 led matrices. Currently, only ARMv7 is tested (Olimexino Lime A10 and Raspberry Pi B+ v1.2)

Tap detection based on piezo. Once event detected (double tap), power output enable PWM, which can drive LED strip for example.

Did you changed regular bulbs by LED, but they shine bit too much? This is the solution! Reduce output power through energy efficient PWM driver!
